Abstract

Purpose

The Mediterranean Diet (MD) is an expression of different Mediterranean food cultures and lifestyles. It is characterized by high consumption of olive oil, vegetables, legumes, whole grain products, fruits and nuts. This paper aims to emphasize on the evolution of human diet from earliest human ancestors to current civilization, the effect of MD on human health and the role of globalization to shift traditional diet, particularly MD to processed foods.

Design/methodology/approach

Different published papers were collected from the internet by using the following phrases: evolution of human diet, human ancestors, the effect of globalization on a regional diet, Mediterranean diet, healthy food, food pyramid, evolution of human diet and effect of globalization on diet. Finally, the papers were read and summarized as a review paper.

Findings

MD has been accepted worldwide owing to its health impact such as prevention and control of type 2 diabetes, anti-inflammatory effects and decrease in the risk of cardiovascular diseases and incidence of Parkinson’s disease and Alzheimer’s disease. However, in conjunction with this discordance between our ancient, genetically determined biology and the nutritional, cultural and activity patterns of contemporary Western populations, many of the so-called diseases of civilization have emerged. Particularly, the food staples and food-processing procedures introduced during the Neolithic and Industrial periods have fundamentally altered nutritional characteristics of ancestral hominin diets. MD is currently under the risk of extinction for a result of the effects of globalization.

Originality/value

The review paper focuses on the evolution of human diet as an effect of globalization on the regional diet with emphasis on the MD. It specifically focuses on the link between diet and earliest human ancestors, about MD and its health benefit, diet pyramid and effect of globalization on regional diet.

Abstract

Purpose

Among the growing number of data mining (DM) techniques, outlier detection has gained importance in many applications and also attracted much attention in recent times. In the past, outlier detection researched papers appeared in a safety care that can view as searching for the needles in the haystack. However, outliers are not always erroneous. Therefore, the purpose of this paper is to investigate the role of outliers in healthcare services in general and patient safety care, in particular.

Design/methodology/approach

It is a combined DM (clustering and the nearest neighbor) technique for outliers’ detection, which provides a clear understanding and meaningful insights to visualize the data behaviors for healthcare safety. The outcomes or the knowledge implicit is vitally essential to a proper clinical decision-making process. The method is important to the semantic, and the novel tactic of patients’ events and situations prove that play a significant role in the process of patient care safety and medications.

Findings

The outcomes of the paper is discussing a novel and integrated methodology, which can be inferring for different biological data analysis. It is discussed as integrated DM techniques to optimize its performance in the field of health and medical science. It is an integrated method of outliers detection that can be extending for searching valuable information and knowledge implicit based on selected patient factors. Based on these facts, outliers are detected as clusters and point events, and novel ideas proposed to empower clinical services in consideration of customers’ satisfactions. It is also essential to be a baseline for further healthcare strategic development and research works.

Research limitations/implications

This paper mainly focussed on outliers detections. Outlier isolation that are essential to investigate the reason how it happened and communications how to mitigate it did not touch. Therefore, the research can be extended more about the hierarchy of patient problems.

Originality/value

DM is a dynamic and successful gateway for discovering useful knowledge for enhancing healthcare performances and patient safety. Clinical data based outlier detection is a basic task to achieve healthcare strategy. Therefore, in this paper, the authors focussed on combined DM techniques for a deep analysis of clinical data, which provide an optimal level of clinical decision-making processes. Proper clinical decisions can obtain in terms of attributes selections that important to know the influential factors or parameters of healthcare services. Therefore, using integrated clustering and nearest neighbors techniques give more acceptable searched such complex data outliers, which could be fundamental to further analysis of healthcare and patient safety situational analysis.

Abstract

Purpose

Within the theoretical context of human security, this United Nations (UN) three‐year research project examines the causes and effects of conflicts in the arid and semi‐arid lands of Northern Kenya. The purpose of this paper is to address the human security concerns arising out of conflict, displacement, migration and poverty. The people who live in the area are mainly nomadic pastoralists.

Design/methodology/approach

A review of previous empirical research and ongoing field studies are used to examine four problem areas: cattle rustling, proliferation of small arms, competition over scarce resources and conflict between refugees and local communities.

Findings

Seeking access to water and green pastures, the nomads generally follow their cattle across the region, and their movement is not confined to Kenya alone. They cross and re‐cross international boundaries to and from Ethiopia, Sudan, Somalia and Uganda resulting in conflicts over water and pasture. Resource competition in a fragile economy has had grave consequences for the economic security of families and internally displaced people.

Originality/value

The North Rift and North Eastern regions of Kenya are the most underdeveloped area of the country and suffer from a high level of human insecurity, with more than three‐quarters of the population living below the poverty line. This UN project seeks an empirical understanding of the causes of conflict and ways to build the capacity of a vulnerable population to gain both freedom from fear and freedom from want.

Abstract

Purpose

This study aims to examine smallholder farmers’ perceptions toward the adoption of climate-smart agriculture (CSA) in smallholder farmers in the Upper Blue Nile Highlands of Ethiopia. Available research focused on profitability and economic constraints alone, disregarding the farmers’ perception of the adoption of CSA innovations. There is relatively little empirical work on farmers’ perceptions of innovations. Hence, a critical research gap that will strengthen CSA innovation research and practice includes understanding farmers’ perceptions about CSA innovations and how these perceptions interact with their adoption.

Design/methodology/approach

A cross-sectional household survey was conducted among 424 smallholder farmers selected from five agro-ecosystems. A structured questionnaire was used to collect primary data and a review of literature and documents was used to collect secondary data. The study used a multivariate probit model to examine perception factors affecting the likelihood of adopting multiple CSA innovations. The dependent variables were eight CSA innovations, while the independent variables were crafted from the three pillars of CSA.

Findings

Major CSA innovations adopted by farmers include improved variety, crop residue management, crop rotation, compost, row planting, soil and water conservation, intercropping and agroforestry. Farmers’ perception toward CSA innovations includes: CSA innovations sustainably increase productivity and income; enhance soil fertility; diversify livestock feed and energy sources; reduce soil erosion, weed infestation and crop failure; enhance soil organic matter, reduce chemical fertilizer use and rehabilitate land. Farmers’ positive perceptions of the benefits of CSA innovations for increasing crop productivity, reducing agricultural vulnerability to climate change and lowering farm greenhouse gas emissions have boosted adoption.

Practical implications

Farmers’ perceptions toward CSA innovations must be enhanced to increase the adoption of CSA innovations in the smallholder agriculture system. The CSA innovation scale-up strategies should focus on farmers’ perception of CSA innovation benefits toward food security, climate change adaption and mitigation outcomes. Awareness of CSA needs the close collaboration of public extension as well as local institutions such as farmers’ training centers.

Originality/value

The study adopts a multivariate probit model that models farmers’ simultaneous CSA innovation choices. Hence, this study contributes to the literature in four significant areas. First, it argues for differential treatment of the perception of smallholder farmers about innovations is needed. Second, it recognizes the interdependence of the adoption of innovations. Third, it directly assesses the farmers’ perception, while others use proxies to measure it. Finally, there are limited or no studies that address the perception of innovations within the lens of adopter perception theory.

Abstract

Purpose

This study aims to investigate the adaptation strategies they practice and the factors that influence their use of adaptation strategies.

Design/methodology/approach

The mixed-method sequential explanatory design was used to triangulate the data collected. Multistage sampling was used to select 400 sampled households for household surveys. Eight focus groups, each with eight to ten participants, and 24 key informants, were specifically chosen based on their farming experiences. Chi-square tests, one-way ANOVA and a binary logit model were used to analyze the data.

Findings

The majority of farmers used simple and low-cost adaptation strategies like changing planting dates, selling livestock and off-farm and nonfarm work. A minority of farmers used advanced adaptation strategies like crop diversification and water harvesting for irrigation. The result further revealed that: the age of the household head, educational status of household heads, farm size, livestock ownership, farming experiences, household income, access to credit and access to climate information significantly influenced the adoption of the adaptation strategies. Public policy should provide water harvesting and irrigation technology, climate-related information and the provision of microcredit facilities to enhance the farmers’ resilience to climate change risks.

Originality/value

Although several studies on climate change adaptation strategies are available, this paper is one of the few studies focusing on a particular agro-ecological zone, an essential precursor to dealing with current and projected climate change in the area. It provides helpful insights for developing successful adaptation policies that improve adaptive capacity and agricultural sustainability in southern Ethiopia’s lowlands.

Abstract

Purpose

Change of climate is attributed to human activity that alters the composition of the global atmosphere observed over comparable periods. The purpose of this paper is to explore smallholder farmers' perceptions of climate change and compare it with meteorological data, as well as to identify perceived adaptation barriers and examine the factors that influence the choice of adaptation options in eastern Ethiopia.

Design/methodology/approach

In total, 384 sample households were chosen from four districts of the zone. A cross-sectional survey was used to conduct the study. Primary data was acquired through key informant interviews, focus group discussions and semistructured interviews, whereas meteorological data was collected from the National Meteorological Service Agency of Ethiopia. A Mann–Kendall statistical test was used to analyze temperature and rainfall trends over 33 years. A multivariate probit (MVP) model was used to identify the determinants of farmers' choice of climate change adaptation strategies.

Findings

The result indicated that temperature was significantly increased, whereas rainfall was significantly reduced over the time span of 33 years. This change in climate over time was consistently perceived by farmers. Smallholder farmers use improved varieties of crops, crop diversification, adjusting planting dates, soil and water conservation practices, reducing livestock holdings, planting trees and small-scale irrigation adaptation strategies. Moreover, this study indicated that sex of the household head, landholding size, livestock ownership, access to extension, access to credit, social capital, market distance, access to climate change-related training, nonfarm income, agroecological setting and poverty status of the households significantly influence farmers’ choice of adaptation strategies.

Research limitations/implications

Further research is required to evaluate the economic impact of each adaptation options on the livelihood of smallholder farmers.

Practical implications

Institutional variables significantly influenced how farmers adapted to climate change, and all of these issues might potentially be addressed by improving institutional service delivery. To improve farm-level adaptation, local authorities are recommended to investigate the institutional service provision system while also taking demographic and agroecological factors in to account.

Originality/value

This study compared farmers' perceptions with temperature and rainfall trend analysis, which has been rarely addressed by other studies. This study adopts an MVP model and indicated the adaptation strategies that complement/substitute strategies each other. Furthermore, this study discovered that the choice of adaptation options differed between poor and nonpoor households, which has been overlooked in previous climate change adaptation research.

Abstract

Background: A range of local social and environmental factors has an impact on farmers' views of climate change and choices on the use of coping mechanisms. This study examines the factors that are limiting farmers' perceptions of climate change and their coping mechanisms in Gimbi district, Western Ethiopia.

Methods: A household survey and focus group discussion were employed to collect relevant data. A total of 402 randomly selected households and six focus group discussions containing 72 participants were used to gather data. Binary logit models were used to analyze the collected data.

Results: Farmers noted that some of the signs of climate change included increasing temperature, erratic rainfall, late onset of rainfall, and early cessation of rainfall. We discovered that there are three distinct sets of climate adaption strategies used by farmers: crop management, soil and water conservation and intensive farm management. The primary determinants of farmers' perceptions of climate change and adaptation techniques were household head age, education, soil fertility, market access, and agricultural training. Age, education, and soil fertility level were the characteristics that significantly impacted farmers' perspectives and coping mechanisms among the primary drivers evaluated in the area. Use of agroforestry, shifting planting dates, and fertilizer application were all essential farming practices used as climate adaptation measures.

Conclusions: Both socioeconomic and environmental factors have found to affect farmers' perceptions of climate change in the area. The existing socioeconomic and environmental factors, in turn, affect their choice of strategies to adapt to climate change. When implementing climate change adaption strategies, it is critical to assess farmers' level of awareness of climate change and their coping strategies, as well as the factors limiting their ability to adapt to climate change.

Abstract

Purpose

The purpose of this paper is to investigate perceptions of smallholder farmers toward the cost-sharing agricultural extension service provision.

Design/methodology/approach

The study used data from a cross-sectional survey, key informants interviews and focused group discussions conducted on 384 farm households from six Kebeles of Eastern Ethiopia.

Findings

The authors find that flexibility and credibility, ability of development agents to address neglected aspects in agricultural production, and reaching diversified groups of farmers as the perceived advantages of the cost-sharing approach. Furthermore, improved knowledge and attitude, enhanced research–extension–farmer linkages, and improved food security and poverty reduction are found to be the three most important impact areas associated with the approach. On the contrary, poor economic status of farmers, high cost of administration and absence of a clear guideline/legislation are found to be the most important constraints. The authors find that increasing farmers’ awareness about the cost-sharing approach and preparing a clear definition of the form, modalities and principles of the cost-sharing extension approach can be a part of the practical solutions to overcome the challenges.

Research limitations/implications

The current research is limited to the investigation of farmers’ perceptions toward paid extension services. The willingness to pay for extension services – using discrete choice experiments – is dealt with in another paper.

Originality/value

The first of its kind in the country, the paper tried to assess farmers’ readiness to try a new extension service delivery. The findings have important implications for policy makers and local level implementers of extension programs.

Abstract

Purpose

The purpose of this study results and recommendations will have a paramount significance for policymakers, policy advocates, development planners and practitioners who may be in need of such information for reconsideration, evaluation and inclusion into their respective development and humanitarian programming and operational strategies. Above all, the study result has further provided the local community with viable adaptation strategies to climate-induced changes in the study area.

Design/methodology/approach

This study was conducted to measure the livelihood vulnerability of Borana pastoralists to climate change and variability in southern Ethiopia. Pastoralists’ households were sampled using multistage sampling techniques. A total of 27 socio-economic and biophysical indicators were used to reflect vulnerability components: adaptive capacity, exposure and sensitivity. Principal component analysis was used to develop weights for indicators and to produce livelihood vulnerability index to classify households according to their level of vulnerability. Ordinal logistic regression was used to identify the determinants of vulnerability to climate-induced stresses.

Findings

The results showed that 24.4% of households were highly vulnerable, 60.3% were moderately vulnerable and 15.3% of households were less vulnerable to climate-induced stresses. Factor estimates of the logistic model further revealed that early warning information, bush encroachment, coping strategy, temperature, drought frequency, provision of humanitarian services and food shortage during the normal season of the year have a significant influence on vulnerability in the study area.

Social implications

The study’s results and recommendations will be of great significance to policymakers, development planners, and practitioners who require such information for reconsideration, evaluation, and inclusion in their respective development and humanitarian program and operational strategies. Most importantly, the study’s findings have provided the local community with practical adaptation strategies to climate-induced changes in the study area.

Originality/value

The study explored pastoralist perception of climate change and variability and measured the livelihood vulnerability of pastoralists’ households to climate change and variability and finally investigated viable adaptation and coping strategies in the study area.
